The genus Serratula L. belongs to Asteraceae family and has 17 taxa in Turkey. In this study,<br />
somatic chromosome numbers were determined in four species of Serratula which grows up<br />
naturally from Turkey. These taxa are Serratula kotschyi Boiss., S. quinquefolia M.Bieb. ex<br />
Willd., S. erucifolia (L.) Boriss. and S. hakkiarica P.H.Davis according to their floristic order.<br />
All species contained somatic chromosome numbers of 2n = 30. The basic chromosome<br />
number of the genus was x = 15. The research has made contribution to the cytotaxonomic<br />
revision of the genus Serratula in Turkey. Somatic chromosome counts were made using<br />
Bs200Pro Image Analysis System.<br />

Genus Erysimum is represented by 70 taxa in Flora of Turkey. 43 of them are endemic to<br />
Turkey. According to Flora of Turkey and recent papers Erysimum echinellum Hand.-Mazz.<br />
and Erysimum dincii Y�ld. are two poorly known endemic species. During the excursion in<br />
2005-2009, the authors were collected lost of specimens belonging to the species. E.<br />
echinellum Hand.–Mazz. was firstly described from Hazarbaba mountain (Elaz��, Turkey) by<br />
Handel-Mazzetti in 1913. After this date, it was recollected from different localities (from<br />
Adana, Sivas, Kayseri, Karaman, Nev�ehir, Kahramanmara� provinces) by the authors. So, its<br />
distribution area has been expanded. The threat category of the species was assessed<br />
according to IUCN criteria and the new threat category proposed for this species. E. dincii<br />
Y�ld. was recently described from Karaman province by �inasi Y�ld�r�ml� in 2008. It was<br />
recollected from different localities (from Ankara, Nev�ehir, Kayseri provinces). The threat<br />
category of the species was assessed according to IUCN criteria and the new threat category<br />
proposed for this species. Morphological descriptions, new localities, distribution maps and<br />
photographs of the species are given. Phytogeographic elements for these two species are<br />
suggested.<br />
